Here, the controller 160 may display the effect selection window 1300 on the looper area 730 on the looper screen 700 . The effect selection window 1300 may include a plurality of effect items 1310 . To the effect items 1310 , audio effects may be individually assigned. That is, audio effects may be preset in the effect items 1310 . Here, each audio effect may be determined by a combination of setting values corresponding to a plurality of audio parameters. That is, according to a change in set values corresponding to at least one of the audio parameters, audio effects may be different from each other.

Next, when any one of the effect items 1310 is selected, the controller 160 may detect it in operation 519 . In operation 521 , the controller 160 may map and store any one of the effect items 1310 to the effect shortened item 1120 . Through this, the controller 160 may map and store any one of the audio effects in the effect shortened item 1120 . Thereafter, the controller 160 may return to FIG. 2 .

Meanwhile, if the effect shortening item 1120 is not selected in operation 515 , the controller 160 may return to FIG. 2 .

Meanwhile, if the storage event is not detected in operation 217 , the controller 160 may proceed to operation 221 .

Subsequently, when an execution event is generated, the controller 160 may detect it in operation 221 . At this time, when the shortcut items 1110 and 1120 are selected on the looper screen 700 , the controller 160 may detect this as an execution event. Here, when a touch gesture is generated in response to the shortcut items 1110 and 1120 , the controller 160 may detect a storage event from the touch gesture. For example, when a touch occurs in the shortcut items 1110 and 1120 , the controller 160 may determine whether the touch holding time, ie, the touch time, is equal to or greater than a preset threshold time. And if the touch time is less than the threshold time, the controller 160 may detect an execution event.

Subsequently, in operation 223 , the controller 160 may short-run at least one of the loop items 741 or any one of the audio effects.

Referring to FIG. 6 , when the loop shortening item 1110 is selected, the controller 160 may detect it in operation 611 . That is, the controller 160 may detect an execution event in response to the loop shortening item 1110 .

Next, the controller 160 may reproduce at least one of the music patterns in operation 613 . In this case, the controller 160 may detect at least one of the loop items 741 in response to the loop shortening item 1110 . Also, the controller 160 may reproduce at least one of the music patterns in response to at least one of the loop items 741 . In this case, the controller 160 may reproduce at least one of the music patterns at once. Alternatively, the controller 160 may repeatedly reproduce at least one of the music patterns. Alternatively, the controller 160 may continuously reproduce at least one of the music patterns. Here, the controller 160 may display the reproduction bit of at least one of the music patterns through the beat indicator 752 . For example, the controller 160 may blink the beat indicator 752 in response to the reproduction bit of at least one of the music patterns. Thereafter, the controller 160 may proceed to operation 615 .

At this time, when at least one of the music patterns is reproduced, the controller 160 may activate at least one of the loop items 741 as shown in FIG. 12 . Here, at least one of the loop items 741 may be switched from the inactive item 810 to the active item 820 . In addition, the controller 160 may output color light in response to the active item 820 . For example, the controller 160 may output color light from at least one of the active item 820 and a peripheral area of the active item 820 . Also, the controller 160 may output color light according to the position of the active item 820 in the loop area 740 . To this end, various colored lights may be individually assigned to the columns of the loop items 741 in the loop area 740 .

Meanwhile, if the loop shortening item 1110 is not selected in operation 611 , the controller 160 may proceed to operation 615 .

Next, when the effect shortening item 1120 is selected, the controller 160 may detect it in operation 615 . That is, the controller 160 may detect an execution event in response to the effect shortened item 1120 .

Next, the controller 160 may apply any one of the audio effects in operation 617 . In this case, the controller 160 may detect any one of the audio effects in response to the effect shortened item 1120 . Also, the controller 160 may apply any one of audio effects to at least one of the music patterns. In addition, the controller 160 may continuously reproduce at least one of the music patterns. Thereafter, the controller 160 may return to FIG. 2 .

Meanwhile, if the effect shortening item 1120 is not selected in operation 615 , the controller 160 may return to FIG. 2 .

Meanwhile, if an execution event is not detected in operation 221 , the controller 160 may proceed to operation 225 .

Finally, when an end event occurs, the controller 160 may detect it in operation 225 . And the controller 160 may end the operation method of the electronic device 100 .

Meanwhile, if the end event is not detected in operation 225 , the controller 160 may return to operation 215 . In addition, the controller 160 may repeatedly perform at least one of operations 215 to 225 .

According to the present invention, the electronic device 100 may play music through the looper function. That is, the electronic device 100 may display the loop items 741 and reproduce music patterns of the loop items 741 in response to input data.
